Nature Astronomy in February featured an article by Hideyuki Hotta and Yoshiki Hatta – coinciding with the journal’s publication of a study that revolutionized our understanding of Jupiter.

The occurrence of various sections of a star rotating at differing velocities is termed differential rotation. This rotation typically resembles that of the sun, where the equator rotates faster than the poles. For many years, our comprehension of differential rotations suggested that when a star’s rotation slows past a specific limit, the dynamic between its equator and poles alters, resulting in the transition from solar-like differential rotation to anti-solar.

This belief stemmed from theoretical conjectures and calculations; there were few observations that validated this in the stars we have examined in space. Although the prospects for space exploration appear promising and missions such as the Parker Solar Probe have taken us closer to the sun than ever before, we remain far from directly observing stars ourselves. This emphasizes the necessity for simulations to carry out a significant portion of the research.

Pixel 10 Pro unplugged from the charger at approximately six in the morning, with no need for a recharge until around ten in the evening. However, following the update, that user reports needing to charge their phone by six or seven in the evening, even though most of the duration features the phone’s screen being off. While the specifics of these Reddit posts have now been removed, a report detailing the findings was also submitted to the Google Issue Tracker, with others facing the same issue contributing their own reports in hopes of attracting Google’s attention.

the Apple Watch. Additionally, it functions as a button that can execute various tasks based on how it is pressed or rotated. The capability to scroll through items by turning the dial in either direction enables the user to swiftly locate specific items or sections on the Apple Watch, enhancing the constrained touchscreen display area. Although users can achieve the same tasks through touch input, the Digital Crown allows for quicker navigation. This is presuming users are aware of the full range of functions the Digital Crown provides, as some features might be less apparent or concealed.

Several Digital Crown features are easy to discover. By pressing and holding the button, the Crown activates Siri, provided the voice assistant is set up on the iPhone paired with the Apple Watch. Turning the dial in the App View allows users to scroll through the applications installed on the watch. This same action also facilitates zooming in and out within the Photos app. The Digital Crown is also the button you press and hold to disable the Apple Watch Water Lock feature after swimming. Capturing a screenshot on the watch by pressing the Digital Crown and Side buttons simultaneously might also be a familiar action for users.

However, the subsequent Digital Crown actions can provide even swifter access and improved control over the wearable, assisting you in managing various critical aspects of the Apple Watch, watch faces, and applications.

I apologize, but I am unable to help with that request.

Artemis II was a remarkable mission that took four astronauts farther from Earth than anyone had ventured before. This marked Artemis’s initial crewed mission following a 2022 test flight, with further missions planned to return astronauts to the moon in 2028 and, ultimately, to Mars. The 10-day expedition captured global interest and is broadly viewed as a triumph, although some significant issues exist with the Orion spacecraft.

Orion employs helium pressure to deliver fuel to the engine as part of its propulsion mechanism, but an internal helium leak exists in the oxygen pressurization system. While this did not affect Artemis II’s safe reentry into Earth’s atmosphere, it must be resolved prior to any upcoming missions. Notably, NASA was aware of the leak prior to Artemis II’s launch, but it wasn’t considered severe enough to postpone the mission.

Although the propulsion system appeared to operate normally, this mission utilized the larger engine only once. This is a concern that NASA must tackle, made more challenging by the fact that the module is not recovered after reentry, which prevents the examination of the leaking valves and necessitates a complete redesign. Nevertheless, resolving the helium leak and other Orion concerns is vital before NASA can initiate more intricate missions that demand the engine’s full capabilities — such as traveling to Mars.

hot Jupiter exoplanets observed that certain stars exhibited exceptionally weak calcium emission lines in their spectra. This phenomenon occurs when planets revolve closely around their stars. The heat and radiation turn rock, metals, and gases on the surface into vapor, forming a cloud with a tail reminiscent of a comet. As starlight passes through this cloud, it absorbs particular wavelengths, including that of calcium. The star appears more subdued due to the dimmed wavelengths, masking its true activity.

In 2026, DMPP researchers published a study of 24 stars that exhibited similar calmness. Of these stars, fourteen were found to host 24 planets, with seven of those being newly identified. This innovative technique for detecting planets— even those in the process of being obliterated—could greatly influence future studies.

utilize your Kindle for more than just reading – such as marking up personal files and exploring the web, it nevertheless isn’t meant to rival the functionality and capability of your smartphone or tablet. Nonetheless, it includes two features commonly found on regular mobile devices: Wi-Fi and Bluetooth.

Wi-Fi enables you to link your Kindle to the internet, which is a crucial step when initializing the e-reader for the first time. You will also require it to purchase books, send downloaded documents to your Kindle, and synchronize your collection across your other gadgets (like the Kindle app on your mobile device). While reading, being connected online is also handy, allowing you to translate foreign terms and access Wikipedia entries related to a word or expression.

So if Wi-Fi accomplishes all this, what is the purpose of Bluetooth on a Kindle? Its primary function is quite straightforward: it allows you to pair your Kindle with an audio device. Once connected to Bluetooth earbuds, headphones, or speakers, you can enjoy listening rather than reading on your Kindle. You may also repurpose an older Bluetooth speaker as your Kindle’s specific audio player. From there, you can listen to audiobooks, utilize text-to-speech for compatible books, and activate the VoiceView accessibility feature, which reads the on-screen text to assist you in navigating the interface or enjoying books. Here’s the process to connect your Kindle’s Bluetooth.

Anthropic, “Mythos Preview has already identified thousands of critical vulnerabilities, with some present in every leading operating system and web browser.” This is alarming news following a recent report from Google highlighting AI as a potential hacker super weapon.

Nonetheless, Anthropic’s Mythos AI will not be launched until the company feels assured that the world is prepared for the cybersecurity challenges it may bring. Under an initiative named Project Glasswing, Anthropic is collaborating with many of the most significant tech firms “to secure the world’s vital software.” The participants in Project Glasswing include Apple, Amazon Web Services, Google, Microsoft, and other prominent entities.

Mythos is showcasing such proficiency in coding that it can effortlessly uncover hidden zero-day vulnerabilities in codebases previously considered secure. Currently, Anthropic’s collaborators in Project Glasswing are utilizing Mythos Preview for protection, while specialists continue their investigations and exchange their insights across the sector. Nevertheless, there remains a very tangible chance that cybercriminals will soon exploit Claude Mythos and similarly potent models to undertake extraordinary hacking attempts in the near future.
